Magnum 6K25e Gigabit Fiber Switch Installation and User Guide (10/07)

Magnum 6K25e units are plug-and-play devices. There is no software configuring necessary to be done for basic operation at installation or for maintenance. The only hardware configuration settings are user options for an UP-LINK Switch (resides inside the unit) on the 6K8-RJ45. Optional Half / Full duplex mode and 10 or 100Mbps selection for the switched ports must be configured through MNS software per unit as per the requirement. The internal functions of both are described below.

Filtering and Forwarding

Each time a packet arrives on one of the switched ports, the decision is taken to either filter or to forward the packet. Packets whose source and destination addresses are on the same port segment will be filtered, constraining them to that one port and relieving the rest of the network from having to process them. A packet whose destination address is on another port segment will be forwarded to the appropriate port, and will not be sent to the other ports where it is not needed. Traffic needed for maintaining the operation of the network (such as occasional multi-cast packets) are forwarded to all ports.

The Magnum 6K25e Switches operate in the store-and-forward switching mode, which eliminates bad packets and enables peak performance to be achieved when there is heavy traffic on the network.

Address Learning

All Magnum 6K25e units have address table capacities of 4K node addresses suitable for use in larger networks. They are self-learning, so as nodes are added, removed or moved from one segment to another, the 6K25e Switch automatically keeps up with node locations.

An address-aging algorithm causes least-used addresses to fall out in favor of frequently-used addresses. To reset the address buffer, cycle power down-and-up.

4.2Status LEDs

For all Magnum 6K25e models :

PWR	: Power LED, ON when external power is applied to the unit.
LK	: Steady ON, Link status for 10 Mbps and 100Mbps operation.
ACT	: ON with port activity for 10 Mbps and 100Mbps operation.
F/H	: Full / Half duplex LED, ON when the port is running full
	duplex, OFF for half duplex.
100/10	: Speed LED, ON when the speed is 100Mbps , OFF when the
	speed is 10 Mbps
